Biomass is an industry term for getting energy by burning wood, and other organic matter. Burning biomass releases carbon emissions, but has been classed as a renewable energy source in the EU and UN legal frameworks, because plant stocks can be replaced with new growth. It has become popular among coal power stations, which switch from coal to biomass in order to convert to renewable energy generation without wasting existing generating plant and infrastructure. Biomass most often refers to plants or plant-based materials that are not used for food or feed, and are specifically called lignocellulosic biomass. As an energy source, biomass can either be used directly via combustion to produce heat, or indirectly after converting it to various forms of biofuel. Conversion of biomass to biofuel can be achieved by different methods which are broadly classified into: thermal, chemical, and biochemical. Some chemical constituents of plant biomass include lignins, cellulose, and hemicellulose.


Biogas typically refers to a mixture of different gases produced by the breakdown of organic matter in the absence of oxygen. Biogas can be produced from raw materials such as agricultural waste, manure, municipal waste, plant material, sewage, green wate or food waste. Biogas is a renewable energy source.Biogas can be compressed, the same way as natural gas is compressed to CNG, and used to power motor or vehicles. In the UK, for example, biogas is estimated to have the potential to replace around 17% of vehicle fuel. It qualifies for renewable energy subsidies in some parts of the world. Biogas can be cleaned and upgraded to natural gas standards, when it becomes bio-methane. Biogas is considered to be a renewable resource because its production-and-use cycle is continuous, and it generates no net carbon dioxide. Organic material grows, is converted and used and then regrows in a continually repeating cycle. From a carbon perspective,

Carbon offset

A carbon offset is a reduction in emissions of carbon dioxide or greenhouse gases made in order to compensate for or to offset an emission made elsewhereOffsets are typically achieved through financial support of projects that reduce the emission of greenhouse gases in the short- or long-term. The most common project type is renewable energy,Offsets are viewed as an important policy tool to maintain stable economies and to improve sustainability.[15] One of the hidden dangers of climate change policy is unequal prices of carbon in the economy, which can cause economic collateral damage if production flows to regions or industries that have a lower price of carbon—unless carbon can be purchased from that area, which offsets effectively permit, equalizing the price


One of the unique aspects of Greenest Energy SW is that we operate buying groups. We have found that more and more businesses like the idea of being part of something that not only benefits them but other businesses to. The purpose of the groups is to use the overall size and power of the Basket to negotiate with suppliers directly. This is an effective way of bringing prices down for the customer. On average this means a 2 to 3% discount. In real terms this can be up to 1p per KWH reduction, which can in some instances mean savings of hundreds or even thousands of pounds a year.

To be part of a buying group all you need to do is ask for a Group Price or if you are considering creating a group then you need to speak to us first. For more information on Buying Groups please contact us direct.
